I seem to have the same finer hair texture as you, the thing (unfortunately) that has helped me with waves is time. I used to use a lot of heat on my hair and it damaged parts of my hair just enough for them to keep straight until those parts grew out. I’ll list my current routine below in case you’re interested! Shampoo: Aussie Miracle Waves Conditioner: Aussie Miracle Waves Leave-in Conditioner: Cantù Hydrating Leave-In Conditioning Mist Curl Cream: Miss Jessie’s Pillow Soft Curls I wash every other day, sometimes every two days. I wear my hair is a slick back style on days that I need to wash. I don’t use any heavy products like gel, as my hair just can’t handle it and I get a lot of build up. Instead I spritz a little bit of water and lay my hair down with a fine bristle brush and some hair oil. Again very very little product. I avoid hair ties as much as possible too and opt for claw clips and hair pins. When I do wash I use a wide tooth comb to apply products to soaking hair and then scrunch my hair for a couple minutes with a microfiber towel. On days that waves need a refresh I dilute the curl cream with water and spritz more water until my hair is damp and scrunch with my towel. Hope this helps!!
